MultiLinestring WKT as defined in "OpenGIS Simple Features Specification for SQL Revision 1.0" published 13 March, 1998. A MultiLinestring is defined in section 2.1.8 and its Well Known Text Representation is documented in section 3.2.5.2. Point WKT as defined in "OpenGIS Simple Features Specification for SQL Revision 1.0" published 13 March, 1998. A Point is defined in section 2.1.3 and its Well Known Text Representation is documented in section 3.2.5.2. The non-integer portion of the identifier for the house, building or other feature which precedes the address number itself, as defined by the official address authority for the given jurisdiction. 1. This element will not be applicable for most addresses. When township-range or other non-numeric geographic index references precede an address number, they are placed in this field. The address number can then be maintained as an integer for sorting and quality control tests. 2. If necessary, the Separator can be used to separate the address number from the prefix or suffix elements in constructing the complete address number. The numeric identifier for a land parcel, house, building or other feature, as defined by the official address authority for the given jurisdiction. 1. The address number is defined as an integer to support address sorting, parity (even/odd) definition, and in/out of address range tests. 2. Special care should be taken with records where the address number is 0 (zero). Occasionally zero is issued as a valid address number (e.g. Zero Prince Street, Alexandria, VA 22314) or it can be imputed (1/2 Fifth Avenue, New York, NY 10003 (for which the address number would be 0 and the suffix would be "1/2")). More often, though, the address number is either missing or non-existent, and null value has been converted to zero. 3. Some addresses may contain letters, fractions, hyphens, decimals and other non-integer content within the complete address number. Those non-integer elements should be placed in the Address Number Prefix if they appear before the site number, or in the Address Number Suffix if they follow the number. 4. The address number must be converted to text when it is combined with the prefix and suffix into a complete address number. 5. If necessary, the Separator can be used to separate the address number from the prefix or suffix elements in constructing the complete address number. The non-integer portion of the identifier for the house, building or other feature which follows the address number itself, as defined by the official address authority for the given jurisdiction. 1. This element will not be applicable for most addresses. When township-range or other non-numeric geographic index references follow an address number, they are placed in this field. The address number can then be maintained as an integer for sorting and quality control tests. 2. If necessary, the Separator can be used to separate the address number from the prefix or suffix elements in constructing the complete address number. A symbol or word required as a separator between components of a complex element or class. The separator is required for address number ranges and for intersection addresses, and it is occasionally needed in constructing complete street numbers. 1. The default separator, an empty space, is implicit and is not shown in the syntaxes of complex elements and classes. 2. An explicit separator is required for address ranges and intersection addresses. 3. Within a given dataset, one value should be used consistently within a given complex element. 4. For complete street numbers, the separator is rarely needed and its use should be minimized. As an alternative, the separator symbol usually can be included with the address number prefix or suffix. 5. The separator is not needed in creating fractions (1/2, etc.) for address number suffixes. 6. Some address parsing softaware permits the use of ampersands to signify intersection addresses. Be wary, though--in many programming languages, ampersands are reserved for other uses, which could complicate data exchange. A word or phrase that precedes or follows all other elements of the street name and modifies it, but is separated from the street name by a street name pre-directional and/or pre-type. The street name pre-modifier is rarely needed and its use should be minimized. The modifier can be included in the Street Name element unless it is separated from the street name by a pre-type or a pre-directional. A word preceding or following the street name that indicates the directional taken by the thoroughfare from an arbitrary starting point, or the sector where it is located. 1. Standard USPS English abbreviations are E, W, S, N, NE, SE, SW, NW 2. Standard USPS Spanish abbreviations are E, O, S, N, NE, SE, SO, NO 3. USPS Publication 28 recomends abbreviating post-directionals. The Address Standards Working Group differs, and recommends storing post-directionals fully spelled out, exactly as given by the local naming authority, to avoid confusion. For example: "N W Jones St": Is it Northwest Jones Street? Ned Walter Jones Street? North Walter Jones Street? The abbreviations create ambiguity. If stored unabbreviated, directionals can be exported as standard abbreviations as needed for mailing and other purposes. often abbreviatable as N often abbreviatable as S often abbreviatable as E often abbreviatable as W often abbreviatable as NE often abbreviateable as NW often abbreviatable as SE often abbreviateable as SW Spanish word often abbreviateable as N Spanish word often abbreviateable as NE Spanish word often abbreviateable as NW Spanish word often abbreviateable as S Spanish word often abbreviateable as SE Spanish word often abbreviateable as SW Spanish word often abbreviateable as E Spanish word often abbreviateable as W Official name of a street as assigned by a local governing authority, or an alternate (alias) name that is used and recognized, excluding street types, directionals, and modifiers. 1. Each jurisdiction should establish its own list of street names and use it as a domain of values to validate addresses. Alternate and Official names are distinguished by the address attribute "Alias Status Attribute" 2. Local addressing authorities are urged to follow consistent internal street naming practices, and to resolve internal street name inconsistencies, especially for numbered streets ("Twentieth" or "20th" ?), internal capitalization ("McIntyre" or "Mcintyre" ?), hyphens, and apostrophes. 3. If alternate or abbreviated versions of street names are needed for a specialized purpose such as mailing or emergency dispatch, they can be created in views or export routines. The element of the complete street name preceding or following the street name element that indicates the type of street. 1. A street may have either a pre-type or a post-type, or neither, but not both. 2. USPS Publication 28 provides the best list of pre-types and post-types, but it is not exhaustive. 2. USPS Publication 28 provides a standard list of street type abbreviations, and recommends their use. The Address Standards Working Group differs, and recommends storing pre-types and post-types fully spelled out, exactly as given by the local naming authority, to avoid confusion. If stored unabbreviated, directionals can be exported as standard abbreviations as needed for mailing and other purposes. 3. Pre-types are much less common than post-types in English. They are typically used for numbered highway routes and roads. They are much more common in Spanish and French language street names. 4. Occasionally a street name may have neither a prefix type or a suffix type (e.g., "Broadway.") 5. Names like "County Road 28", where the street type occurs in the middle of the name, should be treated as a street name with no pre-type or post-type.

The type of structure (when several structures are found at the same address), e.g., Apartment, Tower, Block. Used with Building Identifier to designate one of several structures at a given site. Fits within the general USPS definition of a "secondary address designator" and EPA definitions of "secondary address identifier" The letters, numbers, words or combination thereof used to distinguish one structure from another when several occur at the same address. Used with Building Type to designate one of several structures at a given site. Fits within the USPS defnition of a "secondary address designator" and the general EPA definition of "secondary address identifier" The word describing the horizontal division of a building where an address is located. Used with Floor Identifier to designate which floor of a given structure contains the address. May preceed or follow the floor identifier. Fits within the USPS definition of a "secondary address designator" and the general EPA definition of "secondary address identifier" The number, letter, or word or combination of numbers and letters distinguishing one floor from another within a structure. Used with Floor Type to designate which floor of a given structure contains the address. If only a Floor name appears (such as Mezzanine) it should be parsed as a Floor Identifier rather than as a Floor Type. Fits within the general USPS definition of a "sescondary address designator" and the EPA definitions of "secondary address identifier." The word describing the type of occupancy within a building or structure. Used with the Unit Identifier element to designate one of several occupancy units within a building. The numbers, letters, words, or combination thereof distinguishing one occupancy from another within a given address. Used with the Unit Type to designate different occupancies at the same address. Fits within the USPS definition of "secondary address designator" and the general EPA definition of "secondary address identifier." A mailbox rented from a private Commercial Mail Receiving Agency (CMRA). USPS Pub 28 Section 284: Normally Private Mail Box identifiers, like mailstop codes and other internal mail distribution codes, pertain to the recipient and are not part of the address. "Exception: When the CMRA mailing address contains a secondary address element (e.g. rural route box number, suite, # or other term), the CMRA customer must use Private Mail Box (PMB) when utilizing a three line address format" (see examples above). The name by which a prominent feature is publicly known. Landmarks usually have a street address. A landmark name does not imply official historic landmark status, but simply a commonly used name that substitutes for an address number and street name in identifying the location of a specific building or feature. Generally the use of a landmark's street address is preferable because it is unambiguous. All landmark names should be cross-referenced to a street address or other coordinate location. A named area, sector, or development that is not an incorporated municipality or other governmental unit, such as a neighborhood in a city, or a rural settlement in unincorporated area. Often called "urbanization" in Puerto Rican addressing usage. 1. "Urbanizacion", commonly used in urban areas of Puerto Rico, is an important part of the address. Street names and address ranges are often repeated in a city, especially where a city has annexed older towns; they are distinguished by their urbanizacion or community name. 2. Certain other words can be used in place of "urbanizacion": extenciones, mansiones, reparto, villa, parque, jardine, altura, alturas, colinas, estancias, extension, quintas, sector, terraza, villa, villas. 3. For more information on Puerto Rican addressing conventions, see USPS Publication 28 Section 29, and USPS "Addressing Standards for Puerto Rico and the Virgin Islands". The name of the municipality (city, township, or othe non-county local government) in which the address is physically located. In many places this will be different than the city name used by the U.S. Postal Service. Required by most local governments for tax and services determinations. This will be null for addresses in unincorporated portions of counties. The name given by the U.S. Postal Service to the post office from which mail is delivered to the address. In many places this will be different from the name of the municipality in which the address is physically located. The name given by the U.S. Postal Service to the post office from which mail is delivered to the address. In many places this will be different from the name of the incorporated municipality in which the address is physically located. The primary administrative subdivision of a state in the United States. The primary legal subdivision of the United States, represented by its two letter USPS abbreviation. This is the only element stored in abbreviated form. Alabama Alaska Arizona Arkansas California Colorado Connecticut Delaware District of Columbia Florida Georgia Hawaii Idaho Illinois Indiana Iowa Kansas Kentucky Louisiana Maine Maryland Massachusetts Michigan Minnesota Mississippi Missouri Montana Nebraska Nevada New Hampshire New Jersey New Mexico New York North Carolina North Dakota Ohio Oklahoma Oregon Pennsylvania Rhode Island South Carolina South Dakota Tennessee Texas Utah Vermont Virginia Washington West Virginia Wisconsin Wyoming American Samoa Federated States of Micronesia Guam Marshall Islands Northern Mariana Islands Puerto Rico Palau Virgin Islands Armed Forces Europe, the Middle East, and Canada Armed Forces Pacific Armed Forces Americas (except Canada) A five-digit code that identifies a specific pseudo geographic delivery area. ZIP Codes can represent an area within a state, an area that crosses state boundaries (unusual condition) or a single building or company that has a very high mail volume. "ZIP" is an acronym for Zone Improvement Plan. Zero pad from the left to fill the range as in 01776. A four-digit extension of the five-digit Zip Code that identifies a portion of a carrier route for USPS mail delivery. Zero pad from the left to fill the range as in 0030. The name of the nation in which the address is located. Although the scope of this standard is restricted US addresses, this item is included for two reasons: to facilitate reconciliation with address standards of other nations, and to accommodate files which mix addresses from the US and other nations. USPS Publication28 lists country names and their international postal codes. A box used for receipt of USPS mail. The box may be located in the post office lobby (e.g PO Box), on the customer's premises or other USPS authorized place (e.g. rural route box). The numbers or letters distinguishing one box from another within a post office. May include slash, hyphen or period. A collection of postal boxes served from a single distribution point. This group includes rural routes, highway contract routes, postal service centers, overseas military common mail rooms and military unit numbers. The numbers or letters distinguishing one group of boxes from another within a distribution point. May include hyphen, slash or period. A central point where mail may be picked up by the addressee. Two values are permitted: "General Delivery" (for post offices), and ship's names (for overseas military addresses). A Concatenation of codes found in FIPS 5-2, 6-4, and 55-3 data guides, with a locally defined code that MUST be defined in the metadata. The general format is (expressed as regular expressions) [0-9]{2}[0-9]{3}[0-9]{5}[0-9]{4}. The X coordinate of address location. This might contain information formatted as decimal or as Lat/Long in degrees minutes seconds. In other words do not assume this is numeric. Look to the metadata for the coordinate style and projective parameters used. The Y coordinate of address location. This might contain information formatted as decimal or as Lat/Long in degrees minutes seconds. In other words do not assume this is numeric. Look to the metadata for the coordinate style and projective parameters used. The longitude coordinate of the address location, noted in decimal degrees. For point and polygon features, coordinate pairs typically locate the point of assignment: a centroid point, a point locating the entry to a property, etc. The latitude coordinate of the address location, noted in decimal degrees. For point and polygon features, coordinate pairs typically locate the point of assignment: a centroid point, a point locating the entry to a property, etc. The USNG or US National Grid is an alphanumeric reference system that overlays the Universal Transverse Mercator (UTM) numerical coordinate system. A USNG coordinate consists of three parts, the: 1. Grid Zone Designation (GZD) for worldwide unique geoaddresses (two digits plus one letter, developed from the UTM system). 2. 100,000-meter Square Identification for regional areas (two letters). 3. Grid Coordinates for local areas (always an even number of digits between 2 and 10 depending upon precision necesary to uniquely identify the location). Look to www.fgdc.gov/standards/status/usng.html for a normative definition. Ordinal or ratio ("true") measurement of the height of each level of a building. Ordinal measurements give relative vertical positions: the lowest level of a building is 1, the one above that 2, etc. Ratio measurements are elevations given in terms of a a spatial referencing system. Either method should be described in file-level metadata per FGDC's Content Standard for Geospatial Metadata. The unique identification number assigned to an address by the addressing authority. The ID number must be unique for each address assigned by an addressing authority. This, combined with the FIPS number of the addressing authority, can provide a unique ID for every address in the US. The earliest date on which the address is known to exist. The earliest date on which the address is known to no longer be valid. The type or classification of the address according to the classification standard. The type of feature identified by the address Initial list of feature types: Block, block face, intersection, parcel, building, entrance, unit. The list might be expanded indefinitely to include infrastructure and other features. The Lifecycle status of the address. The life cycle status of the address. Address falls within a theoretical range, but has never been used. Application pending for use of this address (e.g., address tentatively issued for subdivision plat that is not yet fully approved). Address has been issued and is in use. Address was issued, but is now obsolete (e.g. street name has been changed), building was demolished, etc. Whether the address is as given by the official addressing authority (official), or an unofficial variant or equivalent of it (alias). In any of the address classes described in 2.2, the collective name element may have another acceptable form. Some alternate names may be conditional, on attempt, ie if the alias resolves the address no further alternate names should be considered. Other alternate names are always applied, such as official renamings. All alternate names carry a limit of applicability and a timeframe of applicability. The limit of appicability may be a limit to a single zipcode, a naming authorities boundary, such as city or county limits, or a range of address numbers with such a boundary. Upon official renaming of an address, or renumbering of an address, or a series of addresses, the prior, older address will occur in address lists for a period of time and a conversion to current names or current addresses will need to be provided. Such an entity may match a single address or a range of addresses. The alternate name is established by a separate, or the same, naming authority. Such names may apply to any address class, including landmarks. Such names would be established by naming authorities with a geographically larger area of responsibility, containing all or part of a naming authority with a smaller region, such as a state name overlaying a county name or a county name overlaying a city or town name. Examples would be a state highway designation (State Highway 7) overlaid upon locally named roads or a memorial highway overlaid on local road names or state highway names. Local communities hold on to address names much longer than do regional agencies. A community may use a colloquial address name as much as 30 years after that name has either expired or is no longer salient. This entry provides a conversion to a current name. In data processing, entry errors occur. Such errors if frequently encountered may be corrected by a direct match of the error and a substitution to a current name. For data processing efficiency, entities often create alternate names for internal use. When such alternate names are exposed to other entities they need to be resolved to a current name. Address is posted, but not recognized by addressing authority (e.g. vanity address on a building). Address is verified as being invalid, but keeps appearing in address lists. Different from Unoffical Altername Names in that these are known not to exist;Address has been issued and is in use. A status flag, or an explanatory note, for an address that is not correct according to the address schema in which it is located, but is nonetheless a valid address. This field may be used to identify the type of anomaly (e.g. wrong parity, out of sequence, out of range, etc.) rather than simply whether or not it is anomalous. Local jurisdictions may create specific categories for anomalies. The type of address range represented by the data. Address ranges are ambiguous, in that a set of 2 site numbers and a street name can represent either a building, a block face range, a block range, or an entire street range. 1. The terms "actual" or "theoretical" indicate whether the range is based on existing (in-use) addresses or the potential address range (based on a grid or other numbering system) for the given range. 2. Further discussion of ranges is found under Address Range A text description providing more detail on how to identify or find the addressed feature. "A relation between a pair of integers: if both integers are odd or both are even they have the same parity; if one is odd and the other is even they have different parity."1 Odd and even addresses are usually associated with opposite sides of a street. For example, a jurisdiction may assign odd numbers to the right side of the street when moving away from an address axis. A geographic area where the street names conform to a theme. For example, some neighborhoods feature streets named for birds, US presidents or trees. A subset of the complete street name domain applies to this area. Name of the address scheme that operates over a specified area, i.e.: mountain addresses, plains addresses. A description of an Address Scheme that includes business rules about parity, naming conventions, and other matters concerning the assignment and maintenance of an addressing scheme. This element may refer to an address ordinance, Standard Operating Procedures manual or other external document wherein the rules for addresses in a given scheme are written. Location where the address axes meet. Address axes define the boundaries between adjoining zones in address schema. Those zones may be quadrants (northwest, northeast, southeast, southwest) or other geographic divisions. Lowest address numbers occur nearest an axis. Boundary of the area over which an address schema operates. Source from whom the data provider obtained the address, or with whom the data provider validated the address. Important if the data provider did not obtain the address directly from the local authority. The authority (e.g., municipality, county) that created or has jurisdiction over the creation of an address. The addressing authority may or may not be the same as the physical or postal jurisdiction noted for the address. The FIPS or GNIs code for the authority (e.g., municipality, county) that created or has jurisdiction over the creation of an address. The addressing authority may or may not be the same as the physical or postal jurisdiction noted for the address. An action command for incremental datasets. Add indicates that the information is new. DELETE indicates that the information is to be removed. The unparsed accumulation of Postal City, State, and ZIPCode elements. This element is defined solely for use with the General Address class, which is constructed to accommodate and mix addresses of all types (e.g., a general postal mailing list or contact list). Place Name, State Name, Zip Code, and Zip Plus 4, which appear in all address classes, are kept separate from the rest of the address. No longer a parsed datatype. Content still represents it as such. { Complete Address Number (low)*} + { Separator Element *} + { Complete Address Number (high)*} A set of two address numbers, separated by a "Separator", representing the low and high numbers of an address range. An address number range element should be accompanied by an Address Range Type Attribute that describes the type of range presented in this element. Supporting information for the Address The Address Class associated with singlar locations referenced off of a linear feature, having numeric identifiers. The Address Class associated with singlar locations referenced off of a linear feature, lacking numeric identifiers. The outer and the inner landmark classes must be expressed explicitly as landmark names. The inner name is more specific and the Outer name is more general. In the case of Truth Hall Room 306 Howard University". Howard University would be an outer LandmarkName, and Truth hall would be the inner LandmarkName. The inner LandmarkName may conflict with more global landmark names if not distinguished by a more general LandmarkName. The Single Choice Union of all Address Types
